Diamond Enhanced Termination Tape
Propellantless, Passive Deorbit Technology for Small Satellites
With support from Space Force and NASA, PSI is developing its patented diamond-based electron-emissive coating for a variety of space applications.
When exposed to low voltage plasma, the coating develops a negative electron affinity that results in useful emission currents. When applied to an aerodynamic drag tether, the coating substantially increases the electrodynamic drag contribution to tether operation for small sat deorbiting.
- Diamond-based coating
- Passive mode of operation
- Compact size
- Low cost
Benefit to Customer
- Coated tether provides shorter times to deorbit compared to uncoated tether.
- Offers the possibility for orbit-raising, maneuvering and power generation capabilities in future systems.
